We're dividing 78910423 by 191 
We want to divide 78910423 by 191.

On to step 1:
191 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 191

Advancing to step 2:
78 divided by 191 is 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (9) from the dividend, add it to 78, then carry on: 789 / 191

On to step 3:
789 divided by 191 is 4 with a remainder of 25.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 764 from 789, we get 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 191

Step 4:
If we divide 251 by 191, we get 1 and a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 41.0
Deduct 191 from 251 and we're left with 60.
Take the next digit (0) from the dividend and append it to 60, then repeat: 600 / 191

Going ahead to step 5:
600 divided by 191 is 3 with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 413.0
If we take 573 away from 600, we end up with 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 191

Let's proceed to step 6:
The number 191 fits into 274 1 times, leaving a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 4131.0
If we take 191 away from 274, we end up with 83.
Include the next digit (2) from the dividend after 83, then repeat: 832 / 191

On to step 7:
191 goes into 832 4 times with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 41314.0
If we subtract 764 from 832, we get 68.
Grab the next digit (3) from the dividend, add it to 68, then carry on: 683 / 191

Advancing to step 8:
If we divide 683 by 191, we get 3 and a remainder of 110.
The number 3 becomes the next digit in our result. 
Result so far: 413143.0
The remainder is 110 after subtracting 573 from 683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 9:
The number 191 fits into 1100 5 times, leaving a remainder of 145.
Put 5 as the next digit of the answer. 
Result so far: 413143.5
If we take 955 away from 1100, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 10:
The number 191 fits into 1450 7 times, leaving a remainder of 113.
Write down 7 as next digit of the result. 
Result so far: 413143.57
The remainder is 113 after subtracting 1337 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 11:
191 goes into 1130 5 times with a remainder of 175.
The next digit of our result is 5. 
Result so far: 413143.575
Deduct 955 from 1130 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 12:
When dividing 1750 by 191, we get 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 413143.5759
The remainder is 31 after subtracting 1719 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
191 can be fit into 310 1 times, resulting in a remainder of 119.
Use 1 as the next digit of our solution. 
Result so far: 413143.57591
Subtracting 191 from 310 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

On to step 14:
1190 divided by 191 is 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 413143.575916
Deduct 1146 from 1190 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 15:
If we divide 440 by 191, we get 2 and a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 413143.5759162
Subtract 382 from 440 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 16:
580 divided by 191 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 413143.57591623
Subtract 573 from 580 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 413143.57591623 with a balance of 7e-09.
